Genes affected

TP53INP2 (HGNC:16104): (tumor protein p53 inducible nuclear protein 2) The protein encoded by this gene promotes autophagy and is essential for proper autophagosome formation and processing. In addition, the encoded protein can enhance rDNA transcription by helping in the assembly of the POLR1/RNA polymerase I preinitiation complex. Finally, this protein serves as a transcriptional activator for some genes. [provided by RefSeq, Jul 2016]

TP53INP2 links:

NCOA6 (HGNC:15936): (nuclear receptor coactivator 6) The protein encoded by this gene is a transcriptional coactivator that can interact with nuclear hormone receptors to enhance their transcriptional activator functions. This protein has been shown to be involved in the hormone-dependent coactivation of several receptors, including prostanoid, retinoid, vitamin D3, thyroid hormone, and steroid receptors. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jun 2011]

The c.49G>C (p.E17Q) alteration is located in exon 3 (coding exon 1) of the TP53INP2 gene. This alteration results from a G to C substitution at nucleotide position 49, causing the glutamic acid (E) at amino acid position 17 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
